The Philosophy of Biomarkers: Proxies vs. Targets
The conventional approach to health is a numbers game. We are trained to identify a number on a lab report that is outside the "normal" range and then do whatever it takes to force that number back into line. This entire philosophy is built on a profound misunderstanding of what a biomarker is. A biomarker is not the problem itself; it is a proxyāa shadow on the cave wall that gives us a clue about the underlying reality of our metabolic state.
This is where we run headlong into a fundamental rule of systems known as Goodhart's Law: "When a measure becomes a target, it ceases to be a good measure."
Nowhere is this more evident than in the decades-long war on cholesterol. The conventional story is simple: high LDL cholesterol is linked to heart disease, therefore we must lower it. But the bioenergetic view asks the critical question that is so often ignored: why is the cholesterol elevated in the first place? In this model, cholesterol is not the arsonist; it is the fireman arriving at the scene of a blaze. The plaque that forms in arteries is not the cause of the damage, but an adaptive, biological patch used to seal up lesions caused by chronic inflammation and metabolic dysfunction. When we target the fireman, we do nothing to put out the fire.
This faulty logic applies even when a marker appears deceptively low. Consider serum iron. If a blood test shows low iron in the serum, the standard advice is to supplement. But what if the body is intelligently sequestering iron inside tissues to keep it away from pathogens or to prevent it from catalyzing oxidative damage? In this scenario, flooding the system with more iron is the exact opposite of what the body needs.
This is the bioenergetic philosophy of biomarkers: they are adaptive responses, not problems to be "fixed" in isolation. Chronic inflammation, oxidative stress, and mitochondrial dysfunction are the true underlying causes of these abnormal readings. The goal should never be to chemically manipulate a number on a page. The goal must be to restore metabolic and mitochondrial function. When you do that, the body no longer needs to send up these distress signals, and the biomarkers often correct themselves as a natural consequence of restored health.
